Nodejs node-schedule npm 抛出错误“this.job.execute is not a function”

Question

I'm new to nodejs and I have written a nodejs program and scheduling it every minute using the node-schedule. but after running for some time and generating a couple of logs at the console, nodejs throws error that this.job.execute is not a function

here is the code I am using:

var nodeSchedule = require('node-schedule');

runJob();

function runJob(){
    console.log("start");
    nodeSchedule.scheduleJob('0 * * * * *',require('./prodModules.js'));

}

the logs I am getting is:

C:\Users\1060641\Downloads\NodeJS HealthReport\Collector>node src\main\nodejs\collector_main.js
start

C:\Users\1060641\node_modules\node-schedule\lib\schedule.js:177
    this.job.execute();
             ^

TypeError: this.job.execute is not a function
    at Job.invoke (C:\Users\1060641\node_modules\node-schedule\lib\schedule.js:177:14)
    at null._onTimeout (C:\Users\1060641\node_modules\node-schedule\lib\schedule.js:445:11)
    at Timer.listOnTimeout (timers.js:92:15)

I don't think there is anything wrong with my prodModules.js since running it standalone its running fine. Scheduling is throwing errors.

Please help.

Answer 1

The node-scheduler callback must be a function. Change your runJob to something like this:

function runJob() {
    console.log("start");
    nodeSchedule.scheduleJob('0 * * * * *', function () { 
        require('./prodModules.js');
    });
}

Try re-importing 'node-schedule', I ran your code with a fresh import, and it works as expected.

To down import on windows cmd : > npm install node-schedule
